Product details
The black D8-4 front caliper fits the original caliper mounting location on 1965–1982 Chevrolet Corvettes. Its forged aluminum housing carries four stainless pistons and preserves the stock D8 pad format rather than requiring a different pad family. Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977; it is based in Camarillo, California, and its component range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
Use with the correct 11.75-inch-diameter, nominal 1.25-inch-wide rotor and a matching NPT-ended flex line. Inspect clearance inside the actual wheel; a factory year or wheel diameter does not guarantee every wheel shape will clear.
